mother board repair, water damage

Water damage limited to top of the phone; no signs of any water under the top 5 sockets. there was a bunch of corrosion up there but I cleaned it with non-sweeping ultrasonic cleaner. I'm newbie for soldering but assembling the needed tools for this. the extent of my soldering knowledge is from the recent ifixit videos with Jenna. I could use some expert eyes on this to determine what I need to do; parts I will need. Or practical advice that should send in for repair and learn on some other boards. Phone seems fully functional except for the lcd, digitizer, and likely the two camera sockets. I was able to restore fully to iOS 9.0.2. getting into recovery mode (with use of the home button) and iTunes.
